Description

Technical Field

[0001] The utility model relates to the technical field of papermaking machinery auxiliary equipment, in particular to a double-pressure stone roller scraper. Background Art

[0002] The main function of the press section of a paper machine is to use mechanical squeezing to remove as much water as possible from the paper web and to increase the dryness of the paper web before entering the drying section. During the squeezing process, pulp and paper scraps are easily generated on the surface of the stone roller. The pulp and paper scraps fall off the roller body, which may affect the product quality in mild cases or cause paper breakage in severe cases, affecting the efficiency of the paper machine. The second-press stone roller scraper is particularly important for the press section of the four-roller two-press area of ​​the paper machine.

[0003] The stone roller scraper device used in the prior art, especially the stone roller scraper device in the short and long wire papermaking machine, has always been an old-fashioned fixed scraper device. When cleaning the surface of the stone roller, the lifting and lowering of the scraper can only be achieved by the operator through the handle. The scraper body is heavy, the labor intensity of the operator is high, and more than two people are required to operate it together. The patent with the authorization announcement number CN204509861U discloses a papermaking stone roller scraper pressure device, which includes a cylinder seat, a cylinder, a piston rod, a connecting rod and a scraper. The cylinder seat is fixed on the stone roller support seat by screws, the cylinder is installed on the cylinder seat, the connecting rod is connected to the piston rod, and the scraper is installed on the connecting rod. The existing stone roller scraper device has the defect of loose contact of the scraper, which makes the cleaning effect poor. The loose scraper will cause paper breakage and felt rewetting, which will cause the problem of excessive steam consumption in the drying section and low operating efficiency of the paper machine. Utility Model Content

[0004] In order to overcome the defect of loose contact of the scraper in the prior art, the utility model provides a double-pressing stone roller scraper.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a two-stone pressing roller scraper, comprising two stone pressing rollers, the two stone pressing rollers are fixed on a suspension through a bearing seat, an adjustment bracket is provided on the lower right side of the outer side of the bearing seat, the end of the adjustment bracket is hinged with a telescopic bracket, the middle of the adjustment bracket is hinged with a supporting bracket, the other end of the supporting bracket is hinged with the output end of the telescopic bracket, a scraper seat is provided on the side of the supporting bracket, the stone roller scraper is installed in the scraper seat, and a vibration motor is fixed on the scraper seat.

[0006] As a further improvement of the utility model, the adjusting bracket is a telescopic cylinder.

[0007] As a further improvement of the utility model, the scraper seat is provided with a slot for inserting the stone roller scraper.

[0008] As a further improvement of the utility model, the stone roller scraper is fixed on the scraper seat by fastening bolts.

[0009] As a further improvement of the utility model, a limiting plate is provided on the scraper seat.

[0010] As a further improvement of the utility model, the stone roller scraper is a carbon steel scraper.

[0011] Compared with the prior art, the utility model has the beneficial effects: in this scheme, the telescopic bracket is used to push the supporting bracket to move, so as to promote the scraper seat to rotate a certain angle, so that the stone roller scraper on the scraper seat slowly approaches the surface of the second stone pressing roller. After moving to the predetermined position, the telescopic bracket stops, so that the stone roller scraper and the surface of the second stone pressing roller are in close contact. When the second stone pressing roller is performing processing operations, the stone roller scraper can scrape away impurities on the second stone pressing roller, keep the stone roller clean, and improve processing efficiency and product quality.
